Find the engine that fits the airplane—and the owner.

Compatibility is evidence—not a horsepower guess

An engine appears under an aircraft filter only when that exact catalog configuration already names the engine, or when a manufacturer, builder community, or installation source documents the pairing. A documented experimental installation is not the same as an airframe-manufacturer approval. Engine mount, propeller, cooling, cowl, fuel system, electrical system, firewall-forward weight, center of gravity, vibration, and operating limitations still require engineering and regulatory review.

Engine photos are licensed references. Each card identifies whether its image shows the exact model, the same engine family, or only a similar architecture. The accompanying SVG is generated from the selected record's actual cylinder count, layout, cooling type, drive type, and turbo status; neither image should be used as installation or maintenance documentation.

TBO and fuel burn retain their operating context. TBO conditions identify serial-number, generation, overhaul, and calendar restrictions when the manufacturer publishes them. Fuel burn records the associated power setting and RPM when available. A manufacturer estimate stays labeled as an estimate; a published range is shown as a range. If the reviewed source does not publish a defensible value, the selector says “Not published” instead of inventing one.

Production status is checked against official manufacturer catalogs and explicit discontinuation notices. “Not in current lineup” means the exact model was absent from the current catalog; it does not mean parts or service have vanished. “Unconfirmed” is used when the evidence does not support a reliable yes or no. Every engine detail links to its status evidence and shows the date checked.

New is a published or sourced planning reference. The three used conditions are transparent percentage estimates derived from that reference—not appraisals. Engine logs, total time, time since overhaul, calendar age, storage, corrosion, prop strike history, accessories, shipping, and core value can move a real price dramatically.

Vibration, maintenance, and owner relationship are broad comparative guidance based on architecture and support requirements. “Fly-and-forget” means relatively turnkey within this comparison, never maintenance-free. Unknown technical values remain blank and are excluded only when their numeric filter is armed.
